TECHNICAL FIELD

Embodiments of the disclosure relate to the field of communications, andmore particularly, to a resource configuration method for handover, anetwork access point (AP) and a mobile station.

BACKGROUND

An application field of a network system in the future will be extendedto Vehicle to X (V2X) communication, including Vehicle to Vehicle (V2V)communication, Vehicle to Infrastructure (V2I) communication, Vehicle toPedestrian (V2P) communication, Pedestrian to Vehicle (P2V)communication and the like.

V2X communication may effectively improve traffic efficiency, avoidtraffic accidents and reduce operation risks. Researches show that V2Vcommunication may solve about 82% of collisions without casualties andabout 40% of collisions occurring at crossroads in the United States.

In a V2X communication process, a vehicle is required to keep connectionwith a network all the time to effectively receive information of anetwork side, ensure resource allocation reliability and improve datatransmission efficiency. However, in some scenarios, for example, thereis no network coverage, vehicles usually communicate according topreconfigured resources, so that it is impossible to ensure orderedinformation interaction of a large number of connected vehicles, andresource utilization efficiency of a wireless network is reduced to agreat extent. Therefore, V2X communication in the future will exist onthe basis of vehicle-to-network communication in a biggest range, and itis necessary to ensure smooth connections between vehicles and networksto ensure ordered scheduling and resource allocation of the networks forthe vehicles.

In such a process, a vehicle keeps moving and may be faster in somescenarios, so that how to ensure smooth and successful handover of thevehicle between different network APs becomes a key problem urgent to besolved.

A mechanism capable of ensuring handover exists in a conventionalcellular network. However, there exists a longer transmissioninterruption delay in an existing handover flow, and a transient channelchange problem for a mobile station which moves fast and the like maynot be effectively solved.

FIG. 1 is a schematic diagram illustrating a handover process of amobile station according to an embodiment of the disclosure. As shown inFIG. 1, a first network AP 100, a second network AP 200 and a mobilestation 300 are included.

Here, the first network AP 100 and the second network AP 200 maycommunicate through a cellular link, and for example, communicatethrough a communication interface between the first network AP 100 andthe second network AP 200. Here, the communication interface may be anX2 interface.

The mobile station 300 may be in a fast moving state. For example, themobile station 300 is initially located within coverage of a network ofthe first network AP 100, and may directly communicate with the firstnetwork AP 100. Subsequently, the mobile station 300 moves fast andgradually enters coverage of a network of the second network AP 200. Inthis process, the mobile station 300 requires handover of acorresponding transmission resource, which may cause a longertransmission delay.

According to the embodiment of the disclosure, the characteristic ofpredictability of movement of the mobile station is utilized, and ahandover resource is coordinated between the network APs in advance tofacilitate use of the mobile station over the handover resource in ahandover process, so that a handover interruption time may be reduced.

It is to be understood that conditions, manners and the like in theembodiment of the disclosure are divided only for convenient descriptionand should not form specific limits and characteristics in eachcondition and manner may be combined without conflicts.

FIG. 2 is a schematic flowchart illustrating an example of a resourceconfiguration method for handover according to an embodiment of thedisclosure. The method shown in FIG. 2 is executed by a first networkAP, and includes the following operations.

In S110, the first network AP determines handover resource configurationinformation with a second network AP.

Here, the handover resource configuration information may include atleast one of: location information of a physical time-frequency resourceblock, modulation and coding scheme information, configurationinformation of a reference signal or antenna configuration information.

The handover resource configuration information may further includetime-frequency resource configuration information, a transmissionbandwidth and the like, which will not be listed one by one herein.

Optionally, the handover resource configuration information includesconfiguration information of a handover resource used for handover of aserving network AP from the first network AP to the second network AP;and/or the handover resource configuration information includesconfiguration information of a handover resource used for handover ofthe serving network AP from the first network AP to the first network APand the second network AP; and/or the handover resource configurationinformation includes configuration information of a handover resource ofthe first network AP.

It can be understood that at least one other network AP may be deployedaround the first network AP, and the first network AP may directlycommunicate with the at least one other network AP through acommunication interface (for example, an X2 interface).

As a first condition, if there is only one other network AP, i.e., thesecond network AP, around the first network AP, the first network AP isonly required to determine the handover resource configurationinformation with the second network AP in S110.

Optionally, the first network AP may perform coordination with thesecond network AP through the communication interface to determine thehandover resource configuration information.

Here, the first network AP is synchronized with the second network AP,or there is a first fixed timing offset value between the first networkAP and the second network AP.

The first network AP may perform resource coordination with the secondnetwork AP to determine a handover resource pool in a negotiationmanner. For example, a first handover resource pool and a secondhandover resource pool may be determined, wherein the first handoverresource pool may subsequently be sent to the mobile station by thefirst network AP to enable the mobile station to use a handover resourcein the first handover resource pool in a process of handover from thefirst network AP to the second network AP, wherein the second handoverresource pool may subsequently be sent to the mobile station by thesecond network AP to enable the mobile station to use a handoverresource in the second handover resource pool in a process of handoverfrom the second network AP to the first network AP.

In such a manner, the handover resource used by the mobile stationhanded over from the first network AP to the second network AP isdifferent from the handover resource used by the mobile station handedover from the second network AP to the first network AP as much aspossible, so that a resource conflict between different mobile stationsin the handover process may be avoided, resource contention may bereduced, and data transmission efficiency of the mobile station in thehandover process may be ensured better.

As a second condition, if there are multiple (namely at least two) othernetwork APs (including the second network AP) around the first networkAP, the first network AP may determine handover resource configurationinformation with the multiple network APs in S110, wherein the multiplenetwork APs include the second network AP.

Optionally, the first network AP may perform coordination with themultiple network APs through communication interfaces therebetween todetermine the corresponding handover resource configuration information.

As an embodiment, the first network AP may determine common handoverresource configuration information with the multiple network APs. Atthis moment, the first network AP determines a group of handoverresource configuration information.

As another embodiment, the first network AP may determine handoverresource configuration information with each network AP respectively. Atthis moment, the first network AP determines multiple groups of handoverresource configuration information corresponding to the multiple networkAPs one to one.

In S120, the first network AP sends the handover resource configurationinformation to a mobile station.

In the embodiment of the disclosure, the first network AP may send thehandover resource configuration information to the mobile stationthrough a system information broadcast. or the first network AP may sendthe handover resource configuration information to the mobile stationthrough control signaling.

Here, the control signaling may be physical-layer control signaling, andfor example, is a PDCCH.

Here, the first network AP is synchronized with the mobile station. orthere is a second fixed timing offset value between the first network APand the mobile station.

Optionally, as an embodiment, the handover resource configurationinformation may be sent to the mobile station when the mobile stationaccesses to the first network AP. For example, the handover resourceconfiguration information may be sent to the mobile station in a processof random access of the mobile station to the first network AP.

Optionally, as another embodiment, the handover resource configurationinformation may be sent to the mobile station after the mobile stationaccesses to the first network AP. For example, the handover resourceconfiguration information may be sent to the mobile station after theprocess of random access of the mobile station to the first network APis completed.

Optionally, as another embodiment, the handover resource configurationinformation may be sent to the mobile station when it is determined thatthe mobile station will be handed over from the first network AP to thesecond network AP.

Correspondingly, it can be understood that, before S120, the firstnetwork AP may judge whether the mobile station will be handed over, andfor example, judges whether the mobile station will be handed over fromthe first network AP to the second network AP or not.

For example, whether the mobile station will be handed over may bejudged according to strength of a measurement signal reported by themobile station. or whether the mobile station will be handed over may bejudged according to a moving trajectory of the mobile station. orwhether the mobile station will be handed over may be judged accordingto the moving trajectory and moving speed of the mobile station.

It is to be noted that, if the multiple groups of handover resourceconfiguration information corresponding to the multiple network APs oneto one are determined in S110, the handover resource configurationinformation sent to the mobile station by the first network AP in S120should further include identification information of the correspondingnetwork APs.

Optionally, the first network AP may further send second indicationinformation to the mobile station, and the second indication informationincludes at least one of: synchronization information between the firstnetwork AP and the second network AP, speed information of the mobilestation or moving trajectory information of the mobile station. Here,the synchronization information includes uplink synchronizationinformation and downlink synchronization information. Therefore, themobile station may further determine uplink synchronization informationof the second network AP after acquiring the uplink synchronizationinformation, the downlink synchronization information, the speedinformation, the moving trajectory information and the like.

Here, the synchronization information between the first network AP andthe second network AP may include the first timing offset value.Therefore, the mobile station may acquire synchronization information ofthe second network AP on the basis of the first timing offset value inthe synchronization information and a synchronization relationshipbetween the mobile station and the first network AP.

In S130, the first network AP receives handover indication informationsent to the first network AP by the mobile station.

Here, the handover indication information is configured to indicate thatthe mobile station will be handed over. Optionally, the handoverindication information is indicated by one or more reserved informationbits of physical-layer control signaling; or the handover indicationinformation is indicated by MAC-layer signaling; or the handoverindication information is indicated by RRC signaling.

It is to be noted that, in the embodiment of the disclosure, that thehandover indication information is configured to indicate that themobile station will be handed over may include the following conditions.

1: the mobile station will perform network AP handover.

It is to be noted that, in the embodiment of the disclosure, the firstcondition may at least include the following two conditions.

1a: the mobile station is required to be handed over from a presentnetwork AP to another network AP and is disconnected from the presentnetwork AP.

For example, the mobile station communicates with the first network APat present, and the handover indication information may be configured toindicate that the mobile station will communicate with the other networkAP.

1b: the mobile station is required to be handed over from the presentnetwork AP to the present network AP and the other network AP.

For example, the mobile station communicates with the first network APat present, and the handover indication information may be configured toindicate that the mobile station will communicate with the first networkAP and the other network AP.

2: the mobile station will perform network AP resource handover.

For example, if the mobile station uses a first resource of the firstnetwork AP at present, the handover indication information is configuredto indicate that the mobile station will use another resource of thefirst network AP.

In the embodiment of the disclosure, the characteristic of predictabledirectionality of movement of the mobile station is utilized, a conceptof handover resource configuration information is introduced, thehandover resource is coordinated between the network APs in advance, andwhen the mobile station requires handover, the handover resourceconfiguration information may be used for handover, so that a handoverinterruption time is reduced. Furthermore, the mobile station may notifythe first network AP that the mobile station will be handed over throughthe handover indication information, such a manner is higher inflexibility, the mobile station may be handed over when being required,handover efficiency may be improved, the handover interruption time maybe shortened, and meanwhile, the method may improve a user experience.

Optionally, in the embodiment of the disclosure, the first network APmay send first indication information to the mobile station afterreceiving the handover indication information. The first indicationinformation may be configured to indicate the mobile station tocommunicate with the first network AP and/or the second network AP byusing a configuration indicated by the handover resource configurationinformation (wherein, the handover resource configuration informationmay include the handover resource and a related parameter).

It is to be noted that, in the embodiment of the disclosure, thehandover indication information may include handover of multipleconditions mentioned above, and correspondingly, the first indicationinformation may be configured to respond to the handover indicationinformation. The embodiment of the disclosure will be described belowwith the condition that the handover indication information indicatesthat the mobile station will perform network AP handover as an examplein detail.

In the embodiment of the disclosure, there is made such a hypothesisthat the mobile station will perform network AP handover, wherein atarget network AP for handover may be determined by the mobile stationand may also be determined by the first network AP.

(1) The mobile station determines that the mobile station will be handedover to the second network AP (i.e., the target network AP).

Optionally, the first network AP may also receive identificationinformation of the second network AP from the mobile station. The firstnetwork AP may determine that the mobile station will be handed over tothe second network AP according to the identification information andthe handover indication information.

Here, the identification information and the handover indicationinformation may be born in the same message and may be born in twomessages, which will not be limited in the embodiment of the disclosure.

Optionally, if the first network AP also receives the identificationinformation, the first indication information mentioned above may beAcknowledgement (ACK) feedback information.

The first network AP may execute a related operation, for example, anoperation of notifying the second network AP to be prepared for accessof the mobile station, after acquiring that the mobile station will behanded over to the second network AP.

(2) The first network AP determines that the mobile station will behanded over to the second network AP.

Specifically, after the first network AP receives the handoverindication information, first network equipment learns about that themobile station has a network AP handover requirement, and the firstnetwork equipment may determine the target AP.

For example, it is determined that the mobile station will be handedover from the first network AP to the second network AP according to themoving trajectory of the mobile station.

For another example, it is determined that the mobile station will behanded over from the first network AP to the second network AP accordingto the strength of the measurement signal reported by the mobilestation.

For another example, it is determined that the mobile station will behanded over from the first network AP to the second network AP accordingto the moving trajectory and moving speed of the mobile station.

The first network AP may notify the target AP to the mobile stationthrough the first indication information after determining the targetnetwork AP of the mobile station. In other words, when it is determinedthat the mobile station will be handed over from the first network AP tothe second network AP, the first network AP may send the firstindication information to the mobile station.

It is to be noted that, according to the method of the embodiment of thedisclosure, the first network AP may send the handover resourceconfiguration information to the mobile station in advance to enable themobile station to perform handover according to the configurationindicated by the handover resource configuration information when beingrequired to be handed over, so that the handover interruption time maybe reduced. Furthermore, whether the mobile station will be handed overmay be determined by the first network AP and may also be determined bythe mobile station. Correspondingly, the target network AP may bedetermined by the first network AP and may also be determined by themobile station. The solution is high in flexibility and favorable forhandover of the mobile station.

Optionally, the first indication information may be indicated by one ormore reserved information bits of the physical-layer control signaling;or the first indication information is indicated by a new allocatedRNTI; or the first indication information is indicated by a newphysical-layer control signaling format.

It is to be noted that, in the embodiment of the disclosure, thereserved information bit of the physical-layer control signaling mayrefer to a reserved field or reserved bit which is not used andspecifically defined in a physical-layer control signaling formatdefined in an existing protocol.

It is to be noted that, in the embodiment of the disclosure, the newphysical-layer control signaling format is different from thephysical-layer control signaling format defined in the existingprotocol, or may also be understood as a physical-layer controlsignaling format redefined in a future protocol.

It is to be noted that, in the embodiment of the disclosure, the newallocated RNTI is reallocated besides existing RNTIs, and the new RNTImay be specially configured to represent the first indicationinformation.

Optionally, the mobile station may communicate with the first network APand/or the second network AP via the handover resource indicated by thehandover resource configuration information received in S120 afterreceiving the first indication information.

Optionally, the first indication information may be sent to the mobilestation when it is determined that the mobile station will be handedover from the first network AP to the second network AP.

It is to be noted that, if the multiple groups of handover resourceconfiguration information corresponding to the multiple network APs oneto one are determined in S110, the multiple groups of handover resourceconfiguration information and the identification information of thecorresponding network APs are sent to the mobile station in S120. Then,the first indication information in S130 may include the identificationinformation of the network APs.

For example, the first indication information may include theidentification information of the second network AP. Then, afterreceiving the first indication information, the mobile station maydetermine the handover resource configuration information correspondingto the identification information according to the identificationinformation of the second network AP in the first indication informationand perform subsequent communication via the handover resource indicatedby the handover resource configuration information.

Optionally, after S130, the first network AP may receive uplink datasent by the mobile station via the handover resource.

For example, if the mobile station sends a plurality of uplink datapackets which are the same via the handover resource, the first networkAP may receive the plurality of uplink data packets which are the same,determine one of the plurality of uplink data packets as an uplinkreceived data packet and acquire uplink data in the uplink received datapacket.

Here, the first network AP may perform coordination with at least oneother network AP to receive the uplink data sent by the mobile stationvia the handover resource. Here, the at least one other network AP mayinclude the second network AP. That is, the first network AP may performcoordination with the second network AP and receive the uplink data sentby the mobile station via the handover resource.

It is to be noted that, when the first network AP performs coordinatedreceiving with the other network AP, locations and configurations ofphysical resources used when each network AP receives data packets arecompletely the same; or the locations and configurations of the physicalresources used when each network AP receives the data packets arecompletely staggered. Moreover, one data packet is subsequently selectedfrom the received data packets as a received data packet.

In a coordinated receiving process, the first network AP and the atleast one other network AP may use completely the same physical resourceconfiguration information, or the first network AP and the at least oneother network AP may use completely different physical resourceconfiguration information. Here, the at least one other network AP mayinclude the second network AP. That is, the first network AP and thesecond network AP may use completely the same or completely differentphysical resource configuration information.

Optionally, the first network AP may send downlink data to the mobilestation.

For example, the first network AP may send a plurality of downlink datapackets which are the same to the mobile station to enable the mobilestation to determine one of the plurality of downlink data packets as adownlink received data packet and acquire downlink data in the downlinkreceived data packet.

Specifically, in the process of handover of the mobile station from thefirst network AP to the second network AP, the first network AP may sendthe downlink data to the mobile station. Correspondingly, the mobilestation may receive the downlink data via the handover resource.

Here, the first network AP may perform coordination with at least oneother network AP to send the downlink data to the mobile station. Here,the at least one other network AP may include the second network AP.That is, the first network AP may perform coordination with the secondnetwork AP to send the downlink data to the mobile station.

It is to be noted that, when the first network AP performs coordinatedsending with the other network AP, each network AP sends the same datapacket and uses physical resources of which locations and configurationsare the same.

In a coordinated sending process, the first network AP and the at leastone other network AP may use completely the same physical resourceconfiguration information, or the first network AP and the at least oneother network AP may use completely different physical resourceconfiguration information. Here, the at least one other network AP mayinclude the second network AP. That is, the first network AP and thesecond network AP may use completely the same or completely differentphysical resource configuration information.
